Objective: Enter the valley
Following the scene, you’ll be facing a statue. Look on the ground in front of this for a pile of Byzantine Coins . To the right of this at the end of the corridor behind a smaller statue is a crate of Salvage . Another Salvage crate can be found in the corner behind and to the left of the large statue.
Continue down the corridor behind the large statue and as you take the first left, be prepared to jump to avoid a spike trap on the floor.
Enter the water at the end of the passage and dive under, mash the swim fast button to maneuver through the rocky elements below and keep an eye out for a location where you can surface. You’ll need to do so around the halfway point in order to restore Lara’s breath.
Continue through the underwater tunnel until you surface at the end and can take the stairs out of the area.
At the top of the stairs you’ll find yourself in an abandoned ruin. Follow the set path forward until you reach a set of stairs to the left. Before heading up, continue straight ahead to find a box of Ammo and a quiver of Arrows to replenish your supplies.
Return to the stairs and climb them all the way to the top. Use the zip line you find up here for a scene.
